DISCUSSION
TODAY THROUGH WEDNESDAY...
A DRY COLD FRONT MOVING THROUGH THE REGION OVERNIGHT WILL BRING
BREEZY WINDS TO SOUTHEASTERN MONTANA TODAY. LINGERING
PRECIPITATION ALONG THE DAKOTAS BORDER WILL COME TO AN END ONCE
THE FRONT MOVES THROUGH. EXPECT WIDESPREAD GUSTS IN THE 20S AND
30S MPH. HIGHER GUSTS WILL PERSIST ALONG THE DAKOTAS BORDER THIS
AFTERNOON, IN THE 30S AND 40S MPH. THERE IS CURRENTLY A 50 TO 70%
CHANCE FOR A GUST OVER 50 MPH FOR THIS AREA AS WELL.
FRIDAY INTO SATURDAY, A RIDGE OF HIGH PRESSURE IS EXPECTED TO
BUILD OVER THE REGION, BRINGING WARM AND DRY CONDITIONS. DURING
THIS TIME, WINDY CONDITIONS WILL EXIST AT TIMES, ESPECIALLY OVER
THE MOUNTAINS AND FOOTHILLS AND NEAR/NORTH OF THE BIGHORN BASIN
AND BIGHORN CANYON. ON SUNDAY, ANOTHER DRY COLD FRONT WILL END THE
WINDY CONDITIONS ACROSS MUCH OF THE AREA AND BRING SLIGHTLY
COOLER TEMPERATURES AS COMPARED TO SATURDAY.
A LOW AMPLITUDE RIDGE LOOKS TO BUILD IN MONDAY, ALLOWING DRY
CONDITIONS TO CONTINUE. ENSEMBLE FORECASTS SUGGEST A BREAK DOWN OF
THE RIDGE AND LARGE SCALE TROUGHING DEVELOPING OVER THE WESTERN
UNITED STATES BY THE MIDDLE OF THE WEEK. THIS COULD BRING A RETURN
TO COOLER CONDITIONS WITH AN INCREASED CHANCE OF PRECIPITATION BY
TUESDAY OR WEDNESDAY. LA/PM
AVIATION

BRISK NORTHWEST DEVELOP. LOOK FOR NORTH/NORTHWESTERLY WINDS
